|Structure of atomic hydrogen (preprint) by Joseph George - Joseph George|
Present-day atomic theory suggests that electrons in an atom exist around the nucleus as standing matter-waves (or electron clouds) in inner and outer orbitals. However, because this behavior requires electrons to be constantly moving, and because there is no evidence that electrons display this kind of motion, the present-day atomic theory may not be accurate. Here I discuss a conceptual experiment, involving the interaction of light with hydrogen gas, which leads us to assume that, contrary ...

|Structure of hydrogen atom (preprint) Joseph George - Joseph George|
Present-day atomic theory suggests that electrons are continually moving around the nucleus as electron cloud or matter wave. However, since there is no evidence for this kind of electron’s motion, the present-day atomic theory may not be accurate. Here I discuss an experiment, which involves the interaction of light with hydrogen gas, led to assume that, contrary to the present-day belief the electrons or nuclei which in the atoms of a medium have no role in the transmission of light through ...

|Effect of Metal Alloys, Degradation Inhibitors, Temperatures on Thermal Oxidative Stability of CF3O(CF2O)(sub x)(CF2O)(sub y)CF3 Fluids - Jones, William R., Jr.|
Degradation-promoting action of a series of ferrous and titanium alloys on CF3O(CF2O)(sub x)(CF2-CF2O)(sub y)CF3-based Z25 fluids and the inhibition effectiveness of several classes of additives were investigated. Four types of additives-phosphines, phosphates, phospha-s-triazines, and diphosphatetraazacyclooctatetraene-were studied in two batches of Z25 fluid, P28 and P151. In the absence of inhibitors, titanium alloys were more detrimental than the ferrous metals, but the additives were more e...

|CODAC (Cockpit Oriented Display of Aircraft Configurations) version 1.4 user's guide - Bingel, Bradford D.|
The Cockpit Oriented Display of Aircraft Configurations (CODAC) package is an interactive FORTRAN 77 graphics program which produces high quality publication grade hidden line images of three dimensional wireframe objects. The term, Cockpit Oriented, is used because CODAC rotates objects relative to the changing aircraft axis system (rather than about a fixed global axis system) and uses the more familiar directions of yaw, roll, and pitch...

|Potassium metasomatism of volcanic and sedimentary rocks in rift basins, calderas and detachment terranes - Chapin, C. E.|
The chemical, mineralogical, and oxygen-isotopic changes accompanying K-metasomatism are described. The similarities with diagenetic reactions in both deep marine and alkaline, saline-lake environments are noted. The common occurrence of K-metasomatism in upper-plate rocks of detachment terranes indicates that the early stage of severe regional extension causes crustal downwarping and, in arid to semi-arid regions, development of closed hydrographic basins.

|A Parallel Genetic Algorithm for Automated Electronic Circuit Design - Lohn, Jason D.|
We describe a parallel genetic algorithm (GA) that automatically generates circuit designs using evolutionary search. A circuit-construction programming language is introduced and we show how evolution can generate practical analog circuit designs. Our system allows circuit size (number of devices), circuit topology, and device values to be evolved. We present experimental results as applied to analog filter and amplifier design tasks.

|Relationship of the Membrane ATPase from Halobacterium saccharovorum to Vacuolar ATPases - Stan-Lotter, Helga|
Polyclonal antiserum against subunit A (67 kDa) of the vacuolar ATPase from Neurospora crassa reacted with subunit I (87 kDa) from a membrane ATPase of the extremely halophilic archaebacterium Halobacterium saccharovorum. The halobacterial ATPase was inhibited by nitrate and N-ethylmaleimide; the extent of the latter inhibition was diminished in the presence of adenosine di- or triphosphates. 4-Chloro-7-nitrobenzofurazan in- hibited the hatobacterial ATPase also in a nucleotide- protectable mann...

|Development of Improved Surface Integral Methods for Jet Aeroacoustic Predictions - Pilon, Anthony R.|
The accurate prediction of aerodynamically generated noise has become an important goal over the past decade. Aeroacoustics must now be an integral part of the aircraft design process. The direct calculation of aerodynamically generated noise with CFD-like algorithms is plausible. However, large computer time and memory requirements often make these predictions impractical. It is therefore necessary to separate the aeroacoustics problem into two parts, one in which aerodynamic sound sources are ...

Rate coefficients for the reactions of C2H HCN yields products and C2H CH3CN yields products have been measured over the temperature range 262-360 K. These experiments represent an ongoing effort to accurately measure reaction rate coefficients of the ethynyl radical, C2H, relevant to planetary atmospheres such as those of Jupiter and Saturn and its satellite Titan. Laser photolysis of C2H2 is used to produce C2H, and transient infrared laser absorption is employed to measure the decay of C2H to...

|ERIC ED297954: Radioisotopes: Today's Applications. - ERIC|
Radioisotopes are useful because of their three unique characteristics: (1) radiation emission; (2) predictable radioactive lives; and (3) the same chemical properties as the nonradioactive atoms of that element. Researchers are able to "order" a radioisotope with the right radiation, half-life, and chemical property to perform a given task with the knowledge of these three characteristics. This publication includes information on the uses of radioisotopes in medicine for providing doctors with ...
